relative to the normal stack alignment of the target (e.g., when using
ebp as framepointer, all addresses are offset 8 to the stack pointer) in
the temp generator. This enables allocating temps/locals with the correct
alignment as long as the required alignment is not bigger than the
guaranteed stack pointer alignment (fixes mantis #15582 on systems where
the stack pointer is at least aligned to 16 bytes; e.g., not yet on
i386-platforms other than darwin)

they don't have explicit side-effects, and if -Oodeadvalues (part of -O4)
is active (because it can result in the removal of range check errors,
segmentation faults, etc)

(mantis #22665)
+ support "[var wrt ..gotpcrel]" nasm/yasm syntax in intel assembler mode
for GOT-relative accesses on x86-64, + give an error when trying to do
this on win64 (it doesn't have a GOT)
* moved code that give a warning when using GOT-relative accesses to
static data on x86-64 from the AT&T reader to rax86 so it's also
active for the Intel assembler reader
+ added warning when not using GOT-relative accesses (but plain
RIP-relative instead) to global data on non-Win64 x86-64

the result location is a simple location (a single register/reference)
(mantis #22490)
* print an error when accessing "result" in a nostack pure assembler routine
if the result location is not simple

default value (mantis #22343)
* give an error when specifying an invalid default value (e.g. a
floating point number for a longint parameter)
git-svn-id: trunk@22021 -
* check "A op B" and "B op A" again for operators that can be commutative (all binary ones except shl, shr, div, mod, **, / and -)
* also check for Nil for classrefdefs if left side is a pointer (allows "TClass var" <>/= Nil again, after the above changes)
* don't allow overloads for "implicit pointer type <>/= pointer" and the other way around (this fixes non compiling Objective Pascal test tobjc21.pp and also the new toperator87.pp test)
* some formating corrections
+ added test for "TObject <> Pointer"
+ added test for "TClass <>/= Nil"

The changes are built up in a way that all operators on two given types are not allowed if a default implementation for that operator exists. This implies that there is a possibility to have a overload work for (in this order) type A and B, but not for B and A. This is for example the case for Set + Enum (which seems to have a default implementation) where Enum + Set is allowed. The added tests try to detect as many default implementations as feasible, but can't cover everything...

hierarchies from other units that were compiled without debug information
in case not all classes from the hierarchy are explicitly used

(tf_safecall_clearstack is set for it) -> also use pocalls_cdecl for it
and adjust the safecall tests not to try parameter scenarios that are
unsupported for cdecl

overflow (don't know what the y-coordinate is at that point, because the
window may be wider than the artificial screenwidth) (mantis #20880)
git-svn-id: trunk@21925 -
* test/tcg1.pp: rewrote without PIC, was having the same issue (GOT off by 1), additionally Intel syntax part won't compile anyway. This test is about push/pop encoding, not about PIC.

symtable.pas, searchsym_in_class:
* if we found a helper method that has overload defined we should not forget the symbol as there can be a case that no method with that name is defined in the extended class hierarchy
symtable.pas, searchsym_in_record:
* analogous to the above
+ added test given in the issue
+ added analogous test for record helpers

directory cache significantly slows down running the testsuite (most
tests only use very few units, and are located in directories
containing hundreds or thousands of other, unrelated files)

This fixes 64bit shifts on arm with a constant shift value of 0.
The old code would have emitted something like this
mov r0, r0, lsl #32
as 32 is an invalid shift value (and would be wrong anyway) the
assembler declined to assemble the produced source.
The new code will just not emit any code for a shift value of 0.
tests/test/tint642.pp now tests shl/shr 0 on 64 bit values.
tests/webtbs/tw22326.pp is also added as an additional test.

with the enum instance corresponding to ordinal 0 in JVM constructors,
because a virtual method called by a parent constructor may already
have assigned a different value (see tests/test/jvm/tenum2.pp). This
will result in null pointer exceptions when using such fields without
first explicitly assigning a value to them though.
The old behaviour can be restored with the new -CTenumfieldinit command
line parameter
